Figure 1. 18O profile of G. bulloides at Site 976. The depth scale is in meters composite depth (mcd). Switching between the three offset holes is indicated along the depth axis. Also shown are biostratigraphic marker events from de Kaenel et al. (Chap. 13, this volume). Between 181 and 204 mcd (Hole 976B) and 329 and 352 mcd (Hole 976C), core breaks are indicated above the isotope record. Numbers below the isotope record give oxygen isotope stage assignments.
